Description
Building the new Mesos CLI with Python 3.7 and PyInstaller 3.3.1 (our current dependencu) on your machine currently creates a binary that is not working:
➜ build (master) ✔ ./src/mesos Fatal Python error: initfsencoding: unable to load the file system codec zipimport.ZipImportError: can't find module 'encodings' Current thread 0x0000000110e145c0 (most recent call first): [1] 83095 abort ./src/mesos
As seen in https://github.com/pyinstaller/pyinstaller/issues/3219, this is due to PyInstaller.
We need to update the PyInstaller dependency to have a version that supports Python 3.7.
